Millimetre wave propagation and scattering phenomena for automotive radar

Modern automotive radar operates at the mm-wave frequency band and has to provide reliable sensing information about surrounding targets in all weather conditions. The aesthetic requirements for the modern car design and needs for mechanical protections result in the installation of radar sensor behind different types of plastic cover like the...

High Efficiency IQ-sharing Transmitter

Epidemic Mitigation via Awareness Propagation in Multi-layer Network

The pervasiveness of the Internet and smartphones enables individuals to participate in online social networks such Twitter and Facebook, besides the classic physical contact network. Such multi-layer network allows for feedback between networks / layers. For instance, the spread of a biological disease such as Ebola in a physical contact...

T12 Electromagnetic Ballast Modeling And Retrofit LED Tube Driver Design

LED lamps have become increasingly popular in the market thanks to high energy efficiency. Tubular LED lamps are widely adopted to replace conventional linear fluorescent lamps, like T8 and T12. Compared with rewiring of fixtures (remove or bypass the ballast) retrofit LED Tubes (TLED), which can be directly powered by the existing ballast, are...

DTC and TDC IC Design for Ultra-Low-Power ADPLL

The technology scaling favors the Digital PLLs, which is reconfigurable. In the traditional fractional-N ADPLL, whether counter-based or divider based, DCO and TDC are the main two power consuming blocks. Modifying the phase detection part based on phase prediction makes the architecture more energy-efficient. The new architecture leads to the...

Design and Realization of a Digital Baseband Subsystem of Wakeup Receiver for Wireless Sensor Networks

In the development of wireless sensor networks, the lifetime of a sensor node is always a key design consideration. Since the battery in a sensor node can usually not be recharged or changed, power management is an effective way to extend the network lifetime. The wireless transceiver, also regarded as the ‘main radio’, is a relatively power...
